The Red Prison is a roguelike based on the OGL-content of the SRD for 5th edition Dungeons & Dragons. The Basic Rules are (largely) a stripped back version of those rules and this game takes a similar approach.

The game mostly follows those rules faithfully and they are included with the download. Development is still in its early stages and at this stage any available builds are playable but unstable.

Currently the game features four classes (fighter, rogue, wizard and cleric) and four base races with subraces (human, mountain dwarf, hill dwarf, wood elf, high elf, lightfoot halfling and stout halfling).
